    Dear all,
    I had an old Farfisa intercom station https://www.farfisa.com/en/catalogue/intercom-for-df6000-km812w.html (old connection attached).
    The new one is https://www.farfisa.com/en/catalogue/basic-intercom-pt510w.html. (photo attached)

    Pls advise how should I connect the new system?


    Thank you very much!

    You have bought the wrong uniphone. The uniphone PT510W does not match your system.

    Dear sir,
    I've managed to match 2 wires.
    I can hear and can be heard.
    While testing I also somehow managed to open the door and receive the call sound.
    But can't repeat it.

    Added after 32 [minutes]:


    Opened intercom with exposed circuit board and connected wires on a white wall.

Topic summary

LABEL_AI_GENERATED
The discussion concerns replacing an old Farfisa intercom handset with a new PT510W unit on an existing 4-core twisted-pair wiring system. The new PT510W was identified as incompatible with the original installation, and attempts to connect it only partially worked: two wires were matched, allowing audio in both directions, and intermittent door release and call tone functions were observed. After further clarification, a compatible replacement for the DF6000 system was recommended, specifically the Farfisa EX312 model. The final outcome was successful installation of the compatible EX312 intercom, with all functions working correctly.
